Your comment regarding AoC is extreme. They have bugs, they have balance issues... but all of the classes have their place in the game and are quite capable in PVP or PVE if played/spec'd properly (as is expected).
I have to agree with this. Sure there are some issues, but there is certainly nothing game breaking. Every class is fun as heck to play. And its only getting better all the time. I can't speak for Warhammer because I haven't played it, but I'm having a blast with AoC. And considering the amount of people, guilds and guild cities there are on just the one server I play on, I have to say its definitely a big success so far despite all the QQ'ers on forums.
